Frequently Asked Questions (FAQs)

What types of test equipment are commonly used by electricians and engineers?

Typical equipment includes digital multimeters, clamp meters, voltage testers, infrared thermometers, insulation testers and proving units. These tools help verify circuit integrity, measure electrical values and confirm compliance with Australian standards.

How do I choose the right test instrument for my application?

Start by identifying the measurements you need, such as voltage, current, resistance or continuity. Then consider environmental conditions, required safety ratings, industry standards and whether advanced features like thermal imaging or wireless connectivity matter for your workflow.

Why is True-RMS important in test equipment?

True-RMS ensures accurate readings on non-linear loads such as variable speed drives or modern electronic equipment. Without True-RMS capability, measurements can be misleading and may not meet professional or compliance requirements.

How often should test equipment be calibrated?

Most professionals calibrate their instruments every 12 months, or sooner if the device is used heavily or in harsh environments. Regular calibration ensures accuracy, maintains compliance and extends the life of the equipment.

What safety ratings should I look for when selecting test tools?

Look for CAT II, CAT III or CAT IV ratings depending on where the equipment will be used. Higher categories indicate improved protection when working on mains distribution, switchboards or industrial installations.

Can I use the same test equipment for industrial and residential work?

Yes, provided the instrument meets the required safety category and measurement range for both environments. However, industrial applications may demand higher-rated tools with advanced features for greater reliability.
